Product details
Overview
74LVC4T3144PW-Q10J from Nexperia is an automotive-qualified 4-bit dual-supply level-translating buffer with 3-state outputs, supporting bidirectional voltage translation between independent VCC(A) and VCC(B) rails (1.2 V to 5.5 V each). It features three A-to-B channels (A1–A3 → YB1–YB3), one B-to-A channel (B4 → YA4), and an active-low OE referenced to VCC(A). Designed for mixed-voltage automotive subsystems, it enables reliable signal interfacing between 1.8 V microcontrollers and 5.0 V sensor interfaces.
For engineers reviewing the 74LVC4T3144PW-Q10J datasheet, 74LVC4T3144PW-Q10J pinout, 74LVC4T3144PW-Q10J application, or 74LVC4T3144PW-Q10J equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, IOFF-enabled partial power-down capability, suspend-mode behavior during rail loss, and verified 200 Mbps data rate in 3.3 V → 5.0 V translation.
Technical Context
The device implements a fixed-direction level-shifting architecture: An inputs and YA4 output are referenced to VCC(A), while YBn outputs and B4 input are referenced to VCC(B); OE is VCC(A)-referenced and active LOW. This partitioning enables simultaneous translation across two independent voltage domains without internal cross-coupling.
IOFF circuitry actively disables all outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current and enabling safe hot-insertion or partial system power-down. In suspend mode, all outputs enter high-impedance regardless of OE state - a critical feature for automotive domain isolation and fail-safe operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 1.2 V–5.5 V; VCC(B): 1.2 V–5.5 V - supports direct interface between legacy 5 V, modern 3.3 V/2.5 V/1.8 V, and ultra-low-power 1.2 V logic domains. |
| Max Data Rate | 200 Mbps (3.3 V → 5.0 V) - enables high-speed communication between automotive MCU I/O and higher-voltage CAN transceivers or display drivers. |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads without external buffers. |
| IOFF Leakage | ±2 μA max per port during power-down - ensures negligible standby current in battery-sensitive automotive modules. |
| Temperature Range | −40 °C to +125 °C - qualified for under-hood and ADAS ECU environments per AEC-Q100 Grade 1. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP14 (SOT402-1) package: 14-lead plastic thin shrink small outline, 4.4 mm body width, lead pitch 0.65 mm, recommended for automated SMT assembly and space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, VCC(A) | Supply rail A | Powers A-side logic (A1–A3 inputs, YA4 output, OE input); defines voltage reference for those signals. |
| 2–4, A1–A3 | Data inputs (A-side) | Accept logic levels referenced to VCC(A); translate unidirectionally to YB1–YB3 outputs on VCC(B) domain. |
| 5, YA4 | Data output (A-side) | Output referenced to VCC(A); driven by B4 input (VCC(B)-referenced), enabling B→A translation. |
| 6–7, GND | Ground | Common return path for both supply domains; required for noise immunity and IOFF functionality. |
| 8, B4 | Data input (B-side) | Input referenced to VCC(B); drives YA4 output on VCC(A) domain - sole reverse-direction channel. |
| 9, n.c. | No connect | Internally unused pin; must remain floating or grounded per layout best practices - no electrical function. |
| 10–12, YB3–YB1 | Data outputs (B-side) | Outputs referenced to VCC(B); driven by A1–A3 inputs - primary A→B translation path. |
| 13, VCC(B) | Supply rail B | Powers B-side logic (YB1–YB3 outputs, B4 input); defines voltage reference for those signals. |
| 14, OE | Output enable (active LOW) | VCC(A)-referenced control; asserts high-impedance on all outputs (YB1–YB3, YA4) when HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing per stress test conditions. |
| Asymmetric bidirectional translation | Three dedicated A→B channels plus one B→A channel - matches common automotive signal flow (e.g., MCU → sensors/actuators + feedback). |
| IOFF partial power-down | Automatically disables outputs and limits leakage to ±2 μA when either VCC rail collapses - eliminates need for external isolation switches. |
| Suspend mode | Enters high-Z on all outputs if VCC(A) = GND or VCC(B) = GND - ensures fail-safe isolation during power sequencing or fault events. |
| JEDEC-compliant voltage standards | Meets JESD8-11A (1.4–1.6 V), JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (3.0–3.6 V), JESD12-6 (4.5–5.5 V). |
Applications
| ADAS Camera Interface | Body Control Module (BCM) |
|---|---|
Use Scenario: Interfacing a 1.8 V image signal processor (ISP) with a 5.0 V serializer IC in rear-view camera systems. IC Role / Device Role: Translates ISP's parallel pixel clock and data lines (A-side) to serializer's 5.0 V domain (YBn outputs), while feeding serializer status back via B4→YA4. Use Value: Eliminates discrete level-shifters; IOFF prevents backfeed during ISP sleep mode, reducing system standby current by >15 μA. |
Use Scenario: Connecting a 3.3 V microcontroller to legacy 5.0 V LIN transceivers and lamp drivers in door module ECUs. IC Role / Device Role: Buffers MCU GPIOs (A-side) to drive 5.0 V LIN TX and lamp enable signals (YBn), with OE synchronized to MCU reset. Use Value: Enables single-chip voltage translation for 3 critical signals; suspend mode isolates 5 V domain during MCU brownout, preventing bus contention. |
| Infotainment Display Link | Electric Power Steering (EPS) |
Use Scenario: Level-shifting RGB timing signals from a 1.2 V application processor to a 3.3 V display timing controller in digital instrument clusters. IC Role / Device Role: Translates HSYNC/VSYNC/data lanes (A1–A3 → YB1–YB3) while routing touch interrupt (B4 → YA4) back to AP. Use Value: Supports sub-10 ns propagation delay at 1.2 V → 3.3 V, meeting 60 Hz display timing budgets; low 30 μA ICC reduces AP SoC power load. |
Use Scenario: Isolating torque sensor SPI interface (1.8 V) from 5.0 V motor gate driver logic in EPS control units. IC Role / Device Role: Translates SPI clock/MOSI (A1–A2 → YB1–YB2) and routes gate driver fault flag (B4 → YA4) to MCU. Use Value: IOFF blocks fault signal leakage into 1.8 V domain during gate driver power-up; AEC-Q100 Grade 1 ensures operation at 125 °C junction temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply level translating buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | 4-bit bidirectional translator with direction control (DIR); symmetric A↔B paths; no dedicated B→A-only channel. | Requires external DIR signal routing; less optimal for asymmetric signal flows where only one reverse channel is needed. | Prefer when full bidirectional data exchange is required (e.g., I²C bus extension); avoid when fixed A→B + single B→A suffices. |
| TXB0104PWR | Auto-sensing bidirectional translator; no OE pin; relies on data edge detection; higher propagation delay (typ. 12 ns vs. 6.3 ns). | Cannot support synchronous clock translation; unsuitable for timing-critical parallel buses like display or camera interfaces. | Prefer for low-pin-count, low-speed GPIO translation (e.g., button/LED control); avoid for clock/data strobes or >100 Mbps links. |
Compared with SN74AVC4T245QPWRQ1 and TXB0104PWR, the 74LVC4T3144PW-Q10J offers deterministic unidirectional latency, integrated OE control for precise output gating, and superior speed in asymmetric configurations - making it optimal for automotive timing-critical, mixed-domain signal routing where directionality is fixed and predictable.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies independent absolute maximum ratings: VCC(A) and VCC(B) each tolerate −0.5 V to +6.5 V relative to GND. No maximum differential voltage is defined - the device operates correctly with any combination within those individual limits (e.g., VCC(A) = 1.2 V, VCC(B) = 5.5 V is fully supported).
Can OE be driven from a different voltage domain than VCC(A)?
No. OE is explicitly referenced to VCC(A) and must be driven between 0 V and VCC(A). Driving OE from VCC(B) or another rail violates the pin description and may cause undefined behavior or damage due to input clamping diode conduction.
Does the device support hot insertion when one supply is powered and the other is off?
Yes. The IOFF circuitry activates automatically when either VCC(A) or VCC(B) is at GND, disabling outputs and limiting leakage to ±2 μA. This enables safe hot-plug operation in modular automotive subsystems without risk of back-current or latch-up.
How does propagation delay vary with supply voltage combinations?
Propagation delay is supply-dependent: An→YBn delay improves as VCC(B) increases (e.g., 6.3 ns at VCC(B)=5.0 V, 15.6 ns at VCC(B)=1.2 V), while B4→YA4 delay improves as VCC(A) increases (e.g., 6.3 ns at VCC(A)=5.0 V, 15.6 ns at VCC(A)=1.2 V). Full characterization tables cover all valid VCC(A)/VCC(B) pairs across −40 °C to +125 °C.
